Overview

Package uidc provides functions to generate simple time-and-random-based unique identifiers.

It offers functions to generate 64-bit and 128-bit random identifiers in base-36 string format.

The generated IDs are not intended for cryptographic or security-related purposes. Instead, they serve as simple unique identifiers for various use cases.

Functions

func NewID128

func NewID128() string

NewID128 returns a 128-bit unique identifier encoded as a base-36 string. The high 64 bits are derived from the current time; the low 64 bits are random.

Example

package main

import (
	"fmt"

	"github.com/tecnickcom/gogen/pkg/uidc"
)

func main() {
	v := uidc.NewID128()

	fmt.Println(v)
}

func NewID64

func NewID64() string

NewID64 returns a 64-bit unique ID encoded as a base-36 string. The upper 32 bits contain a timestamp and the lower 32 bits are random. The timestamp epoch is January 1st of the current decade's starting year.

Example

package main

import (
	"fmt"

	"github.com/tecnickcom/gogen/pkg/uidc"
)

func main() {
	v := uidc.NewID64()

	fmt.Println(v)
}
